一、概述 一级品锆英石精矿是一种矿物纯度相当高的精矿,品位(Zr·Hf)O_2≥65％,精矿中锆英石的矿物量要求大于97％以上。生产实践表明,在选矿过程中石英、电气石、石榴子石、钛铁矿等伴生矿物是较易于和锆英石分离的,影响锆英石精矿质量的杂质矿物主要是金红石、独居石和少量的磷钇矿。这些杂质是相应矿物的细粒部分,由于粒度细,导电性或导磁性又较弱,因此难于在电
First, an overview of a product Zirconite concentrate is a very high purity ore concentrate, grade (Zr · Hf) O_2 ≥ 65%, concentrate ore mineral content requirements greater than 97%. Production practice shows that quartz, tourmaline, garnet, ilmenite and other associated minerals are easier to separate from the zircon in mineral processing. Impurity minerals that affect the quality of the zircon concentrate are mainly rutile, monazite and small amount Of xenotime. These impurities are the fine-grained part of the corresponding mineral, which is difficult due to the fine grain size, the electrical conductivity or the permeability,
